TEMPE, Ariz. -- Tyrann Mathieu returned to practice for the Arizona Cardinals on Wednesday and said he was optimistic that he would be able to play when the team faces the Vikings in Minnesota.Coach Bruce Arians also confirmed after practice that wide receiver Jaron Brown has signed an extension that puts him under contract through next season.Brown is out for the season with a knee injury.We love him as a football player, Arians said. It looks like hell be fine health-wise, gives him another year. Hes earned it. Really happy for him and its good for us because hes a quality special teams player and a real quality receiver.The signing gives the team some protection should the Cardinals lose wide receiver Michael Floyd, who becomes a free agent at the end of this season.Jarons a guy you dont want to lose, quarterback Carson Palmer said. What he brings to the team, because he can play special teams, he plays every spot at receiver. Hes got speed, hes physical, he catches the ball. He catches 50-50 balls very well. Just a very, very well-rounded receiver.Browns signing was first reported by azcentralsports.Mathieu was limited in practice but said afterward that his shoulder felt fine. He was still wearing a brace on the knee that was surgically repaired late last season but was meeting with the doctor to discuss taking it off, which would greatly aid the mobility that is so crucial to the way he plays the game.Of courses Id rather play without it, he said, but I dont want to do anything that puts me in harms way, so Ill talk to him. Im sure well negotiate something.The defensive back was sidelined with a shoulder subluxation in Arizonas loss at Carolina on Oct. 30 and missed Sundays 23-20 win over San Francisco.He said removing the brace would clear another hurdle as he tries to get back to his aggressive Honey Badger performances of the past.The shoulder injury, he said, was just another challenge.Life frustrates sometimes, Mathieu said. Youve just got to deal with it. Cant get too high or too low. Its just another challenge for me. I embrace all those challenges.The way Mathieu talked, his participation in Sundays game was no sure thing.Ill see how I feel at the end of the week and if Im at 100 percent, or very close to it, Ill play Sunday, he said. If not, Ill hold back. ... Im optimistic I will play. I try to look on the bright side of everything.Mathieu was asked about the perception that hes handling this shoulder setback better than he did such problems earlier in his career.I dont know, he said. From the outside looking in maybe, but its frustrating on the inside, obviously. A lot of noise. You try to tune that out. Just another challenge for me. I embrace it.The Cardinals defense ranks second in the NFL, allowing 295.2 yards per game, but Mathieu said the team doesnt have the swagger it exhibited in last years 13-3 season.At times weve had swagger. We have had confidence, he said. Were just playing inconsistent right now. Weve just got to get that consistency back. Once we get that back, Im sure well be rolling.Theyd better get rolling soon. At 4-4-1, the Cardinals cant afford many more stumbles if they want to challenge for a playoff berth.After Sundays game against a Minnesota team hungry for a win after four straight losses, the Cardinals go to Atlanta to face the NFC South-leading Falcons.Game notesLarry Fitzgerald didnt practice due to knee and ankle injuries but Arians said he remains confident his star wide receiver will play Sunday. ...

Green (hamstring) and running back Giovani Bernard (knee) were injured in last Sundays 16-12 loss to the Buffalo Bills. Despite those injuries, Ravens head coach John Harbaugh expects another hard-fought game against a rival he has not beaten since Nov. 10, 2013.We respect the Bengals, obviously, Harbaugh said. We have not beat them for a while. It is a big game for us. It is a big challenge for us. They have always been tough for us as long as I have been here. Im sure (they were tough) before that as well. It is a rivalry game, a division game.Baltimore (5-5) has struggled to contain Green throughout his career. In eight games against the Ravens, Green has caught 41 passes for 726 yards with six touchdowns. Cincinnati has won five of those eight contests.The Ravens have a revamped defense that is second in the NFL, allowing 295.1 yards per game.Baltimore could get another boost with the return of linebacker Elvis Dumervil, who has not played since Oct. 9 against the Redskins because of a foot injury.While the Ravens are looking to tighten their grip on first place in the division, Cincinnati (3-6-1) is simply trying to salvage its season. After managing a 27-27 tie against the Washington Redskins in London on Oct. 30, the Bengals lost their next two games by a combined five points.We havent won close games, Cincinnati head coach Marvin Lewis said. Weve had opportunities in the fourth quarter of football games. Weve had leads. Weve had opportunities, and we havent closed the games out.With Green out of the lineup. Baltimore can turn its focus to shutting down Bengals tight end Tyler Eifert, who missed the first six games of the season with an ankle injury. Rookie wide receiver Tyler Boyd also will likely get more targets.The onus will be on Cincinnati quarterback Andy Dalton to get them the ball whilee facing an aggressive Ravens defense that has 23 sacks and 11 interceptions through 10 games.ddddddddddddI feel like it is your typical Baltimore defense, Dalton said. They are big up front, they do a really good job against the run, and they get you in third-and-long situations, so they are good on third down. That is the style, and that is the way I know Baltimore has been for a long time.The Ravens and Bengals have a similar offense. Both teams are able to move the ball, but struggle finding the end zone. Baltimore and Cincinnati are each averaging 19.9 points per game, tied for 25th in the league.The Bengals, however, are just 1-4 on the road this season.We have a lot of football ahead, and we have a big football game for us come Sunday in Baltimore, Lewis said.One of the keys for Baltimore will be establishing an effective running game to wear down the Bengals. Terrance West and rookie Kenneth Dixon have gotten better as the season progressed. However, penalties and late-game deficits has limited their opportunities.Ravens quarterback Joe Flacco, who has also played better over the past three weeks, will also look to take some shots downfield to prevent Cincinnati from crowding the box.We are trying to get everybody involved as much as we can, Flacco said. When you are short on numbers, you obviously cant do as much as you would like to. I do not know if that has had a direct impact on it, but it may have affected it a little bit.Harbaugh is 7-9 all-time against the Bengals. The Ravens have not won an AFC North title since 2012. Cincinnati has won two of the past three division crowns. The importance of this game is not lost on Harbaugh or his players.We want to start fast, but mainly, we just want to play good football -- complementary football, winning football, in all three phases and playing together, Ravens safety Eric Weddle said. If we can do that, well have a good shot. ' ' '
